FILTERING DEHYDRATOR FITTED WITH WASHING DEVICE

摘要

PROBLEM TO BE SOLVED: To perform the washing of the interior of a filtering dehydrator by self-washing function reutilizing a filtrate generated at a time of filtering dehydration without relying on a means for introducing washing water from the outside. SOLUTION: In a fittering dehydrator wherein the spiral delivery mechanism 6 ranging from a rear solid-liquid mixture charging port 7 to a front solid discharge port 8 is provided to the upper part of a filtrate housing tank 1 having a filtrate discharge pipe 2 disposed at the lower part thereof to be led out therefrom through a flooding weir 3 and solid-liquid separation is performed by the rotation of the spiral delivery mechanism 6 and the eccentric rotary motion of a laminated disk, an underwater pump 13 operated by the signal of a liquid level sensor 17 is arranged to the lower part in the filtrate housing tank 1 and a discharge pipe 14 is led out upwardly from the liquid surface of the tank 1 to mount a washing nozzle 15 on the leading end part of the discharge pipe and the return stirring pipe 16 branched from the discharge pipe 14 to be opened to the liquid in the tank 1 is turned downward.
